GRAIN-BINDER.

SPECIFICATION formingl part of Letters Patent No. 248,401, dated October 18, 1881.

Application filed April 533, 1881. (Model.)

To all whom it may concern:

Be it known that I, JOHN E. BUX'roN, a citizen of the United States, residing at Owatonna, inthe county of Steele and State of Minnesota, have invented certainl new and useful Improvements in Grain-Binders; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part ot' this specification.

Figure l is a perspective view of the device. Fig. 2 is a top-plan view. Fig. 3 is a central crosssection on line x of Fig. 2. Fig. 4 is a bottom plan, showing the springs which help actuate the needle and cord moving arm. Fig. 5 is a detail view showing the knotter. Fig. 6 is a detail view showing the connection between shafts E and I. Fig. 7 is adetail view, in side elevation, showing some of the operative parts.

The present invention relates to that class ofgrain-binderskuown asthe cord7 or twine binders; and the novelty consists in the detail ofthe construction and the combination ofthe parts which compose it, as will now be set forth in detail.

In the accompanying drawings, A denotes any suitable frame or carriage in which thel binderis mounted; and B, the usual floor, properly shaped to allow easy passage for the grain from the reception to the delivery end.

The packer-arms c are curved projections extending from a disk, C, two or more of which disks are mounted on a horizontal shaft, I), extending from side to side ot' the machine. Motion is given to this by any suitable power. As the grain is delivered in the machine it is carried forward by the revolving lingers o until sufficient has accumulated to form a bundle or gavel, when the mass will press so hard against the compressor-arm E in the rear part ofthe machine'as to force it outward. This communicates motion to the shaft E in the upper and rear part, and causes the cam F at its end to turn slowly forward. The pin g of the pivoted arm G moves in the slot f of said cam, swinging said arm horizontally against the clutch-wheel H on shaft I, which .is revolved by proper conneclion with the main shaft D, and causes itto engage with the part fi of the clutch fixed on said shaft, and thus motion is carried by the arm i and link K to the arm in of the bent shaft in', connected with curved needle-arm M. Thus said arm M is raised up through the slot bin the door of the machine and pressed against the gavel, forming itinto a proper shape and carrying the cord over the bundle. The cord is brought over the revolving knotter N, which has an open-mouthed cutting-notch, n., in it for the purpose of hohling the cord. This knotter has a pinion, a', on its shank, and is so mounted in the frame that it is actuated by the segment-gear o ou the wheel or disk O, which has motion together with .the shaft I through the part i and wheel H. The segment-gear is so arranged that it actuates the knotter just as the needle-arm has brought the cord into proper position over the gavel or bundle to be tied. The cord is held between the grasper-bar P and the slotted arm R, and is cut by the V-shaped knife p of the grasper-bar.

The spring i' serves to keep the holder normally away from the kuotting-hook and to allow it to be moved up slightly toward the hook as the cord is needed in the operation of tying the knot, said movement being caused by the pull on the cord as it is being looped around the knotter. The action ofthe spring then is to cause the knot to be tied closely and under tension. The holding land cutting bar is slid forward as the knot is completed, so as to release the old end and allow the cord extending from the point of the binderarm to the knotter to fall into the notch in said bar. The bar is then retracted, andthe cord is thereby cut on the side toward theknotterandclainped on the other side, ready foranother binding operation. W'hile the gavel is being delivered from the machine the raised portion or segmental projection o on the wheel O bears against the straight side of the seniicircular revolving portion u of the head of the shaft of the knotter N, and thus the knotter is held firmly in position, as now shown in Fig. 3. So soon as this projection o passes by this side of a the rack o on the wheel O actuates the pinion a and revolves the knot-ter, and when the rack ceases to operate, the arm i on the shaft comes against the flange n" on said piece n, and gives it a quarter-turn back, placing it in position to be reversed when the end of said portion o strikes it and acts on it, as above described. By the retracting motion communicated to the grasp er-bar P from the lever q. to which it is pivoted, and which is moved by the cam-slotted wheel Q, revolved by shaft I, on which it is fixed, the cord is drawn through the cutter-slot r in the arm R and severed. Simultaneously, or nearly so, with this act the arm I on the shaft I, which has been slowly moving under the projection c of the compressor-arm E, is released therefrom, and motion is communicated to the shaft E by the link S, connecting with the crank-arm e at the end of the shaft, and actuated by the spurwheel t on the end of shaft I, engaging with its hooked bent end. This revolution of the shaft E causes` the arm Eto be moved outward and brings the arms U, which project upward and inward from said shaft E', into the rear ot' the gavel or bundle, and these then carry it forward and ontot' the machine. When the two arms throw the bundle from the machine the knetter turns one-fourth round and the knot is drawn ofi' the knotting-hook, and by means of the sharp edge in the point of' knotting-hook the. loop or tongue is cut and clears itself from the knotter, so if the sharp edge should not cut the loop the loop will slip out ol' the front when the knotter is reversed into position at right. angles with the needlearm.

It should be noted that the action of the cam-arm I causes at first the compressor-arm to be brought slightly toward the needle-arm, and thusinsures thepacking together and shaping of the gavel.

The flaring or flan ged ends u of the deliveryarms U materially aid in the effectual and safe delivery of the bundle from the machine.

At each side of the door of the machine are spring guide-arms V, which are hinged at the rear end and project out to the front, and are adapted to be set at any desired angle by the rod o and screw fv. As the gavel comes into the narrowing passage iliade by these springguides the grain is brought lengthwise into even and good shape. Then the cam-arm I is released from the projection c of the compressor-arm, the crank-arm t', by its travel, causes the arm m beneath the floor of the machine to retract the needle-arm M, which is accordingly carried down through the slot b under the machine and into position to be again brought forward and operated as above set forth.

The cord-moving armVVis notched on its end, and acts in conjunction with the needlearm M in the ,usual manner. The springs .1: on the shafts of needle-arm and cord-armT insure the eicieney ot' their operation.

The guide-rods y will serve to keep the grain from getting into the machinery as it passes along from its delivery to the exit end. The hinged plate or leafz, under the packer-wheel C, has springs z to keep it level with the floor of the machine. When this plate is hinged at its lower edge the springs will be so placed as not to throw the upper edge of the plate above the bed or floor. It may sometimes be found advisable to hinge the plate on its upper edge and let the springs act on the lower. The detail of all this construction will readily suggest itself to any one skilled in this class of de vices. This plate is of value when wet or matted grain or any clogging substance is passed under the packing-fingers, as it will give sutiiciently to prevent any accident to the said fingers or machine.

The spring a" on the shaft E serves to press the shaft over, so as to insure the action of the cam F. The spring causes the arm S to act with certainty.

The ends of the compressor-arm E may be made a little flaring, to insure its eicient action.

The packer C, being made ofa solid disk and having the projections or arms c, will be found exceedingly strong and durable.

Having thus described my invention, what I consider new, and desire to secure by Letters Patent, is-

1. The knetter N, having an open-mouthed cutting-notch, n, in its lower end, and pinion n', combined with the wheel O, having gear o and projection o,and grasper P, having knife p, and bar R, slotted at. r', all substantially as and for the purposes set forth.

2. The combination of arms E and U, shaft El, cam F, clutch H. piece i, and pivoted arm G, with shaft I, needle-arm M, connected with and operated by said shaft- I, substantially as shown and described.

3. In combination with the revolving packer C, a hinged section, e, or portion of the floor of the hinder provided with a spring, substantially as shown and described.

4. 1n combination with the tloor B, the spring guide-arms V at the side, adjustable by rods fu and set screws o', substantially as set forth.

5. The knotter N, having pinion n and the open-mouthed cutting-notch mat its lowerend, all substantially as shown and described.

6. rlhe combination of arms E and U, shaft E', cani F, clutch H, piece t', pivoted arm G, and shaft I, with grooved wheel Q, lever q. grasper P, having knife p, bar R, and spring r, substantially as set forth.
